Kevin ★★★★★

The thermal black oxide finish on these gives them a nice, consistent look for tooling projects, and the flat head sits flush without any wobble. I've used about twenty so far in a jig setup and the #5-40 threads cut clean every time with the hex drive.

Brian ★★★★★

These little flat heads torqued down smooth and clean into my jig fixture without stripping, even at 3/4" length in tight spots. The thermal black oxide finish is holding up nicely so far against shop grime and occasional oil.

Olivia A. ★★★★★

The black oxide finish on these #5-40s is even and consistent across all 100 pieces, and the flat heads sit flush without any wobble in my precision assembly work. Socket drive grabs cleanly with a hex key, no stripped corners after several tightenings.
